Troubleshooting Launcher and Kubernetes#

RStudio is now Posit!

Our professional products have been renamed to Posit Connect, Posit Workbench, Posit Package Manager, Posit Cloud, and Posit Academy so it’s easier for folks to understand that we support more than just R. Please review our Blog post/FAQ to answer commonly asked questions about the rebrand.

If you are having issues when integrating Workbench with Kubernetes, then you can use the following troubleshooting steps to perform diagnostic tests, ensure that your configuration settings are valid, and verify that your Kubernetes cluster and environment is properly configured for Posit Workbench, formerly RStudio Workbench, and Launcher.
